Grand jury probe into lethal drug mix-up to resume in March

OKLAHOMA CITY (AP) —

A multicounty grand jury investigating how the wrong lethal injection drug was delivered to Oklahoma's death row for the last two scheduled executions says it is not ready to release its findings.

The grand jury met for three days this week and issued an interim report on Friday indicating it was unable to complete their investigations. The report noted the grand jury heard testimony from witnesses in several different matters.

The grand jury recessed until its next session March 29-31. Grand jury proceedings are secret, and witnesses are typically prohibited from discussing their testimony.

A court ordered a halt to all executions in Oklahoma while Attorney General Scott Pruitt's office investigates how the wrong drug was used in one lethal injection in January 2015 and delivered for another in September.
